Multi-mode memory module and memory component

A memory module comprising:

• a memory rank including a plurality of memory components, wherein the plurality of memory components includes a first memory component and a second memory component each comprising:
• a plurality of memory component data ports that are shared between the first memory component and the second memory component;
• a respective memory core to store data;
• and
• a respective data interface to transfer data between the respective memory core and the plurality of memory component data ports, the respective data interface supporting a first data width mode in which the respective data interface transfers data at a first bit width and a first burst length via a first set of the plurality of memory component data ports, the respective data interface supporting a second data width mode in which the respective data interface transfers data at a second bit width and second burst length via a second set of the plurality of memory component data ports,
• a plurality of memory module data pins to transfer the data between the plurality of memory component data ports for all of the plurality of memory components of the memory rank and a memory controller.

A memory module comprising:

• a memory rank including a plurality of memory components, wherein the plurality of memory components includes a first memory component and a second memory component each comprising:
• a plurality of data port means that are shared between the first memory component and the second memory component;
• a respective memory means to store data;
• and
• a respective interface means to transfer data between the respective memory means and the plurality of data port means, the respective interface means supporting a first data width mode in which the respective interface means transfers data at a first bit width and a first burst length via a first set of the plurality of data port means, the respective interface means supporting a second data width mode in which the respective interface means transfers data at a second bit width and second burst length via a second set of the plurality of data port means;
• a plurality of data pin means to transfer the data between the plurality of data port means for all of the plurality of memory components of the memory rank and a memory controller.
